over the years we have found some brands die quicker then others. IKEA's seem to really die quick for instance.
When we first converted every light in our house our electric bill instantly went down $20 a month. Worth it to me!! You may not notice one or two bulbs, but if you do every bulb you will notice.
For the person that mentioned the ceiling fan - we found some that are ok for ceiling fans - they are able to be dimmed and can withstand the motion. I am sorry I don't remember where my husband got them, but they do make them!
They also make some that are in the shape of globe lights in the bathroom. We like our LED lights in there though. And our solatube in the one bathroom without windows (kinda like a sky light, but a round tube that collects sunlight so it's brighter then a skylight would be).
